My implant ordeal

I went to get a contraceptive implant a couple of months ago and I don't know whether to say I regret it. Why? Now my period never stops. I keep bleeding and bleeding day in day out I'm even tired. I've reported to my Doctor who gave me a couple treatments to stop it. It worked for a month or two and and started again. I went back to my doctor and now it never even responds to the medications again.

Any ideas or suggestions? I want to go and remove it.
